A distinctive species, although confusion with the smaller and less elongate Birch Shieldbug E. interstinctus is possible. The lateral extensions of the pronotum are larger inA. haemorrhoidale, and are marked with red, while the scutellumis green and the abdomen frequently red-tipped.Overwinters as an adult, emerging and mating in the
spring. The larvae occur May-October, feeding mainly on hawthorn
berries, although a range of other deciduous trees are also used,
inlcuding oak, hazel and birch. The new generation is complete from August/September or even later; adults may become darker before hibernation.

Common and widespread in mixed woodlands across Britain and Ireland, becoming somewhat scarcer in Scotland.Adult: All yearLength 13-15 mm
